Abstract

The utility model discloses a handcart used for collecting high tension switchgear voltage signals, comprising a chassis trolley which is provided with a voltage transformer. The voltage transformer comprises an A-phase contact arm, a B-phase contact arm, a C-phase contact arm, a first coil and a second coil which are covered in a same insulating casing; the A-phase contact arm is in electrical connection with the incoming terminal of the first coil; the outgoing terminal of the first coil is in electrical connection with the B-phase contact arm after electrical connection with the incoming terminal of the second coil; the outgoing terminal of the second coil is in electrical connection with the C-phase contact arm; the front ends of the A-phase contact arm, B-phase contact arm, and C-phase contact arm are all provided with a contact; the intermediate parts of the A-phase contact arm, B-phase contact arm, and C-phase contact arm are all provided with a fuse; springs are arranged between the contacts and the fuses. The handcart has a compact structure and a small size and can match a high tension switchgear with a smaller broadband.

Description

A kind of handcart that gathers high-voltage switch gear counter voltage signal

Technical field

The utility model relates to the auxiliary equipment of high-tension switch cabinet, especially a kind of handcart that gathers high-voltage switch gear counter voltage signal.

Background technology

Conventionally, gather the voltage signal that high-tension switch cabinet three is alternate, two voltage transformers need to be installed on handcart, due to the installation site of two voltage transformers and the restriction of insulation gap, such handcart width is larger, more than generally will reaching 650mm.And at present, the width of existing part switch cubicle is less than 600mm, the high-tension switch cabinet that therefore handcart of this traditional collection high-voltage switch gear counter voltage signal can not be less with broadband supports the use.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of handcart that gathers high-voltage switch gear counter voltage signal, compact conformation, and volume is little, and high-tension switch cabinet that can be less with broadband supports the use.

For achieving the above object, the technical solution of the utility model is: a kind of handcart that gathers high-voltage switch gear counter voltage signal, comprise chassis vehicle, voltage transformer is housed above chassis vehicle, described voltage transformer comprises A phase contact arm, B phase contact arm, C phase contact arm and the first coil, the second coil, A phase contact arm, B phase contact arm, C phase contact arm, the first coil and the second coil are coated in same insulation crust, A phase contact arm is electrically connected to the end of incoming cables of the first coil, First Line finish lead and the second coil end of incoming cables are electrically connected to B phase contact arm after being electrically connected to again, the second finish lead is electrically connected to C phase contact arm.

Further improve, the front end of A phase contact arm, B phase contact arm, C phase contact arm is equipped with contact, and fuse is all equipped with in the centre of A phase contact arm, B phase contact arm, C phase contact arm, between described contact and described fuse, stage clip is housed.Improve the contact performance between A phase contact arm, B phase contact arm, C phase contact arm and high-tension switch cabinet bus, and circuit is protected.

Preferred described insulation shell consists of epoxy resin.

Further improve, the top of described chassis vehicle front end is fixed with panel, and the aviation plug of 58 pins is housed on panel.

Further improve, on described panel, be also provided with Sign Board.

The utility model is due to A phase contact arm, B phase contact arm, C phase contact arm, the first coil and the second coil are coated in same insulation crust, A phase contact arm is electrically connected to the end of incoming cables of the first coil simultaneously, First Line finish lead and the second coil end of incoming cables are electrically connected to B phase contact arm after being electrically connected to again, and the second finish lead is electrically connected to C phase contact arm; Being equal to an A phase contact arm, B phase contact arm, C phase contact arm and two voltage transformers carries out integrated, guarantee again the insulation gap between A phase contact arm, B phase contact arm, C phase contact arm, its structure is very compact, volume is little, therefore the width of whole handcart can be done littlely, and high-tension switch cabinet that can be less with broadband supports the use.

Accompanying drawing explanation
